  The message control device 20 controls message transmission. The message control device 20 relays messages between the first messaging system 10 and the second messaging system 30. Hereinafter, a case where the MMS terminal 30a is a transmission terminal and the mobile terminal 10a is a reception terminal will be described as an example. The transmitting terminal is a terminal device that transmits a message, and the receiving terminal is a terminal device that receives a message.

  As shown in FIG. 2, the message control device 20 includes a message server interface 21, an MMS relay / server interface 22, a receiving condition database 23a, a transmitting condition database 23b, a terminal information database 24, a registration unit 25, A message control unit 26, a message storage unit 27, and an indirect transmission control unit 28.

  The message server interface 21 is an interface with the message server 10d. The MMS relay / server interface 22 is an interface with the MMS relay / server 30d. The message server interface 21 and the MMS relay / server interface 22 receive a control message from a terminal device such as the mobile terminal 10 a or the MMS terminal 30 a and input it to the registration unit 25.

  The control message received by the message control device 20 is registered in the condition notification message for notifying the reception side condition or the transmission side condition, the terminal information notification message for notifying the terminal information related to the terminal device, and the message control device 20. There is a reference message that inquires about the receiving side condition or the transmitting side condition. The condition notification message includes a reception side condition or a transmission side condition. The receiving side condition is a condition related to a transmission method of a message when the terminal device becomes a receiving terminal to the receiving terminal. The transmission-side condition is a condition related to a transmission method of a message to the reception terminal when the terminal device becomes the transmission terminal.

  As a method for transmitting a message to a receiving terminal, for example, there are direct transmission and indirect transmission. Indirect transmission is a method in which a message addressed to a receiving terminal is stored in the message storage unit 27, the storage destination is notified to the receiving terminal, and when a message request is received from the receiving terminal, the stored message is transmitted to the receiving terminal. . The direct transmission is a method of transmitting a message addressed to the receiving terminal to the receiving terminal without storing the message in the message storage unit 27 and notifying the receiving terminal of the storage destination. The message storage unit 27 is a message storage unit that stores a message.

  The reception-side condition and the transmission-side condition include a determination condition for determining the transmission method and a transmission method that is specified when the determination condition is met. The decision conditions are, for example, message address, message format, presence / absence of data attached to the message, data format, message priority, message importance, character string included in the message, message capacity, etc. Use to set. The receiving side condition includes at least one of the message source address, the message format, the presence / absence of data attached to the message, the data format, the priority of the message, the importance of the message, and the character string included in the message. It is preferable to set using one. The transmission condition is preferably set using at least one of message priority, message importance, and a character string included in the message.

  The message address includes a transmission source address and a transmission destination address. The transmission source address is used for setting the reception side condition, and the transmission destination address is used for setting the transmission side condition. The message format includes multipart / mixed, multipart / related, multipart / alternative, and the like. The data attached to the message includes an attached file. Data formats include JPEG format and MPEG format. The message priority is the priority for sending a message. The importance of the message is the importance of the content of the message. The priority and importance of the message can be specified using control data indicating the priority and importance. As a specific character string included in the message, for example, a character string indicating priority and importance such as “urgent”, “emergency”, and “important” can be designated. The transmission method designates either direct transmission or indirect transmission. When data is attached to a message, the capacity of the message is the sum of the capacity of the message itself and the capacity of the attached data.

  For example, the receiving-side condition and the transmitting-side condition based on the address are “transmission source address“ @abc. xyz. com ”is included,“ send directly ”,“ destination address is “123 @ abc. xyz. com ", indirect transmission" can be set. In this way, the determination condition can be set for some or all of the addresses. The receiving side condition and the transmitting side condition based on the message format can be set as “indirect transmission when the format is“ multipart / mixed ”” or “direct transmission when the format is“ multipart / related ”. .

  The conditions on the receiving side and the sending side based on the presence or absence of data attached to the message and its format are “indirect transmission when a file is attached to the message”, “JPEG file is attached to the message. In this case, it can be set such as “direct transmission” or “indirect transmission when an MPEG file is attached to the message”.

  For the receiving side condition and the transmitting side condition based on the priority and importance of the message, when the control data indicating the priority and importance is in three stages, for example, “high, medium, low”, “priority is“ high ”. It can be set to “directly transmit when“ is ”or“ indirectly transmit when importance is “medium” or lower ”. As described above, the determination condition may be set by specifying the priority order or the importance level, or may be set by specifying the priority order or the threshold value of the importance level. The receiving condition based on the character string is "If the subject or text contains" Urgent "or" Emergency ", send directly", "Subject or text contains" Important " If it is, you can set it to "Indirect transmission". As described above, the determination condition can be set by designating a part including a character string, such as a subject or a body.

  The determination condition may be set by combining a plurality of items. For example, the condition on the receiving side and the condition on the transmitting side are “transmission source address“ @abc. xyz. com ”is included and the priority is“ medium or lower ”,“ indirect transmission ”,“ destination address is “123 @ abc. xyz. ”com” and when the importance is “high”, send directly ”,“ when the format is “multipart / mixed” and the subject or text contains the text “Urgent”, send directly ”,“ When an MPEG format file is attached to the message and the message capacity exceeds 1 kbyte, the message is indirectly transmitted ”, and a plurality of items can be combined and set.

  A plurality of receiving conditions can be set for one terminal device. Similarly, a plurality of transmission side conditions can be set for one terminal device. In this case, the receiving condition is a priority order used for determining the transmission method and is given a priority order among the receiving condition of the terminal device. Similarly, the transmission side condition is given a priority order used for determining the transmission method, and the priority order in the transmission side condition of the terminal device is given. Hereinafter, the priority order in the reception-side condition of one terminal apparatus and the priority order in the transmission-side condition of one terminal apparatus are referred to as “intra-terminal priority order”. For example, it is possible to assign numbers to the reception-side conditions and the transmission-side conditions in descending order of intra-terminal priority.

  The terminal information notification message includes terminal information related to a terminal device such as the mobile terminal 10a or the MMS terminal 30a. The terminal information notification message includes, as terminal information, information for setting the processing capability of the terminal device, the priority order of the terminal device (hereinafter referred to as “setting information”), and the like. The processing capability of the terminal device includes, for example, a message format, a format of data attached to the message, and a processing capability related to the message capacity. The processing capability relating to the message format and the data format can be indicated by combining the message format and the data format with the types of processing possible for the message and data in that format. The processing capacity related to the message capacity can be indicated by combining the type of processing and the capacity of messages that can be processed. Examples of processing types include reception processing, display processing, and processing processing. The capacity of a message that can be displayed can be determined by the screen size that can be displayed, for example.

  The priority order of the terminal device is a priority order in which the reception-side condition and the transmission-side condition of the terminal device are selected as usage conditions. The use condition is a condition used for determining a transmission method of a message to a receiving terminal. The priority order of the terminal devices can be set according to the messaging system to which the terminal device subscribes, the type of service, the service fee to be paid, and the like. For example, when a telecommunications carrier that operates the first messaging system 10 also operates the message control device 20, a terminal device that subscribes to the first messaging system 10 is set to a higher priority, or a terminal device that has a high service fee. The higher priority can be set. Therefore, the setting information includes a messaging system to which the terminal device subscribes, a type of service, a service fee to be paid, and the like.

  The address of the message control device 20 is set as the transmission destination address of the control message. In the present embodiment, the message control device 20 accepts a notification or inquiry of a reception-side condition “system @ recipient domain” as a transmission destination address of a condition notification message including a reception-side condition or a reference message that inquires a reception-side condition. Is used. For the destination address of the condition notification message including the transmission side condition and the reference message for inquiring the transmission side condition, the “system @ sender domain” that the message control device 20 receives the notification and inquiry of the transmission side condition is used. Therefore, whether the condition notification message notifies the reception side condition or the transmission side condition, or whether the reference message inquires about the reception side condition or the transmission side condition, the condition notification message or This can be determined based on the destination address of the reference message. As a transmission destination address of the terminal information notification message, “system @ message control device domain” in which the message control device 20 receives the terminal information is used.

  The receiving condition, the transmitting condition, or the terminal information is set in the body of the control message. In the body of the condition notification message, the reception side condition or the transmission side condition is set in the order of “transmission method, determination condition”. Further, the determination condition includes “message address, message format, presence / absence of data attached to the message or the format of the data, message priority, message importance, character string included in the message, character string "Part, message capacity". Further, when one terminal device notifies a plurality of reception-side conditions and a plurality of transmission-side conditions, an in-terminal priority is assigned to the reception-side conditions and transmission-side conditions included in the condition notification message. In this case, in the body of the condition notification message, the receiving side condition and the transmitting side condition and the in-terminal priority are set in the order of “transmission method, determination condition, in-terminal priority”. “*” Is set for items not used for the determination condition. An item for which “*” is set is not used as a determination condition and is not considered as a reception condition or a transmission condition.

  For example, when the body of the condition notification message whose destination address is set to “system @ recipient domain” is “directly abc@domain.com, *, *, *, *, *, *, *”, “The source address is“ abc @ domain. In the case of “com”, the reception side condition of “direct transmission” is indicated. If the body of the condition notification message is “indirect, *, *, MPEG, *, *, *, *, *,” or “the indirect transmission is performed when an MPEG file is attached to the message” And the sending condition. If the text of the condition notification message is "Direct, *, *, *, *, *, Urgent, Subject or text, *", "If the subject or text contains the string" Emergency ", send directly "Receiving side condition" and "transmitting side condition".

  If the body of the condition notification message whose destination address is set to “system @ sender domain” is “directly abc@domain.com, *, MPEG, *, *, *, *, *”, “The destination address is“ abc @ domain. com ”and a direct transmission is performed when a JPEG file is attached to the message. If the body of the condition notification message is "Direct, *, *, None, High, *, *, *, *", the condition of the receiving side such as "Send directly when there is no attached data and the priority is high" Indicates the sending side condition. When the message of the condition notification message is “indirect, *, *, *, medium or lower, *, *, *,> 1k”, “when priority is medium or lower and the message capacity exceeds 1 kbytes” "Indirect transmission" indicates a receiving side condition and a transmitting side condition. If the text of the condition notification message is "Direct, *, *, None, *, *, Urgent, Subject or Body, *", "Subject or body contains the string" Urgent "and is attached to the message This indicates a reception-side condition or a transmission-side condition of “transmit directly when there is no data”. Thus, by setting the determination conditions included in the text of the condition notification message for a plurality of items, it is possible to indicate a determination condition that combines a plurality of items.

  Also, for example, when assigning numbers to the receiving-side conditions and the transmitting-side conditions in ascending order from the highest terminal priority, the condition notification message text is “directly *, *, *, *, high, *, In the case of *, *, 1), the receiving side condition and the transmitting side condition that “directly transmit when the importance is“ high ”” and the priority in the terminal of the receiving side condition and the transmitting side condition are the first. Yes, indicates the highest.

When there is no contradiction, the registration unit 25 associates a plurality of receiving-side conditions and the in-terminal priority with the receiving-side condition database 23a in association with the address of the terminal device, and a plurality of transmitting-side conditions and the in-terminal priority. Is registered in the transmission side condition database 23b.

  When there is a contradiction, when a plurality of reception-side conditions or a plurality of transmission-side conditions are acquired by a plurality of condition notification messages, the registration unit 25 determines that the notified reception-side conditions, transmission-side conditions, and in-terminal priority are Because of the contradiction, a confirmation message for inquiring which condition or in-terminal priority is correct is created and input to the message server interface 21 and the MMS relay / server interface 22 to instruct transmission to the terminal device. Further, when a plurality of reception-side conditions and a plurality of transmission-side conditions are acquired by using the reception-side condition setting page and the transmission-side condition setting page, the registration unit 25 sends the notified reception-side conditions and transmission-side conditions. Since the conditions and in-terminal priorities are inconsistent, a confirmation page for inquiring which conditions and in-terminal priorities are correct is created and input to the message server interface 21 and the MMS relay / server interface 22 to the terminal device. Instruct to send. Then, the registration unit 25 registers the correct reception-side conditions, transmission-side conditions, and in-terminal priorities in the reception-side condition database 23a and the transmission-side condition database 23b based on the response to the confirmation message and the confirmation result for the confirmation page. .

  Furthermore, the registration unit 25 sets the priority order of the terminal device based on the acquired setting information. The registration unit 25 registers the set priority order of the terminal device in the terminal information database 24 in association with the address of the terminal device.

  The registration unit 25 receives a reception condition, a transmission condition, an in-terminal priority, and terminal information for a terminal device for which reception condition, transmission condition, and terminal information are already registered. In the side condition database 23a, the transmission side condition database 23b, and the terminal information database 24, the newly acquired reception side condition, transmission side condition, in-terminal priority, and terminal information are registered and updated. Also, the registration unit 25 registers and updates the priority order of the terminal device set based on the newly acquired setting information in the terminal information database 24.

  The registration unit 25 acquires a reference message from the message server interface 21 and the MMS relay / server interface 22. The registration unit 25 searches the reception-side condition database 23a or the transmission-side condition database 23b on the basis of the transmission source address of the reference message, and receives the reception-side conditions of the terminal device that has made an inquiry and the priority within the terminal, or , Acquire the transmission-side condition and its in-terminal priority. The registration unit 25 creates a reference response message addressed to the inquiring terminal device, including the acquired receiving condition and its in-terminal priority, or transmitting condition and its in-terminal priority, and the message server interface 21 , Input to the MMS relay / server interface 22 and instruct transmission to the terminal device. In this way, the registration unit 25 moves the receiving-side conditions stored in the receiving-side condition database 23a and its in-terminal priority, or the transmitting-side conditions and its in-terminal priority stored in the transmitting-side condition database 23b. Notification is made to a terminal device such as the terminal 10a or the MMS terminal 30a. Therefore, the mobile terminal 10a and the MMS terminal 30a can refer to the reception-side conditions and transmission-side conditions registered in the message control device 20, and their intra-terminal priorities.

  The message control unit 26 selects at least one of the reception-side condition or the transmission-side condition as a use condition used for determining the transmission method, and determines a message transmission method to the receiving terminal based on the selected use condition. And transmission control means for controlling the transmission of the message according to the determination result. The message control unit 26 acquires a message from the MMS terminal 30a to the mobile terminal 10a from the MMS relay / server interface 22. The message control unit 26 first selects use conditions. The message control unit 26 selects the use condition based on at least one of the priority order of the receiving terminal and the sending terminal, the priority order of the receiving side condition and the sending side condition, and the use condition designation by the receiving terminal or the sending terminal. Is preferred. According to this, the message control device 20 considers the priority of the terminal device such as the mobile terminal 10a and the MMS terminal 30a, the priority of the reception side condition and the transmission side condition itself, and the use condition in consideration of the request of the terminal device. Can be selected.

  When selecting based on the priority order of the receiving terminal and the transmitting terminal, the message control unit 26 searches the terminal information database 24 based on the transmission destination address of the acquired message, and acquires the priority order of the receiving terminal. Further, the message control unit 26 searches the terminal information database 24 based on the transmission source address of the message, and acquires the priority order of the transmission terminal. The message control unit 26 compares the acquired priority of the receiving terminal with the priority of the transmitting terminal. When the priority of the receiving terminal is high, the message control unit 26 selects the receiving side condition as the use condition. When the priority of the transmitting terminal is high, the message control unit 26 selects the transmission side condition as the use condition. When the priority order of the receiving terminal and the transmitting terminal is the same, the message control unit 26 selects the receiving side condition and the transmitting side condition as usage conditions.

  When selecting based on the priority order of the reception side condition and the transmission side condition, the message control apparatus 20 sets the priority order in advance which of the reception side condition or the transmission side condition is used. When the priority of the receiving condition is set high, the message control unit 26 searches the receiving condition database 23a based on the acquired transmission destination address of the message. If the receiving side condition is registered, the message control unit 26 selects the receiving side condition as a use condition. The message control unit 26 searches the transmission side condition database 24 based on the transmission source address of the acquired message only when the reception side condition is not registered. If the transmission side condition is registered, the message control unit 26 selects the transmission side condition as a use condition. Similarly, when the priority of the transmission side condition is set high, the message control unit 26 first checks whether the transmission side condition is registered in the transmission side condition database 23b, and the transmission side condition is registered. Then, the transmission side condition is selected as the use condition. The message control unit 26 selects the reception-side condition as the use condition only when the transmission-side condition is not registered and the reception-side condition is registered in the reception-side condition database 23a.

  In addition, when selecting based on the priority order of the reception side condition and the transmission side condition, the message control unit 26 determines the priority order based on the contents of the reception side condition and the transmission side condition, and selects the use condition. Also good. For example, the message control unit 26 can determine the priority order of the reception-side condition and the transmission-side condition according to the items used for the reception-side condition and the transmission-side condition determination condition. In this case, the message control device 20 sets the priority order of items used for the determination condition. The message control unit 26 searches the reception condition database 23a based on the acquired transmission destination address of the message, and acquires the reception condition. Further, the message control unit 26 searches the transmission side condition database 23b based on the transmission source address of the message, and acquires the transmission side condition. The message control unit 26 compares the determination conditions of the receiving side condition and the transmitting side condition, determines that the item having a higher priority is higher in priority, and selects it as the usage condition. When the message control unit 26 determines that the priority order of the conditions is equal, the message control unit 26 selects the reception-side condition and the transmission-side condition as usage conditions. For example, when the priority is set higher than the message format, the receiving side condition defines the importance level, and the transmitting side condition defines the message format, The message control unit 26 selects only the receiving side condition as the use condition.

  When selecting based on designation of use conditions by the receiving terminal, the message control unit 26 inquires of the receiving terminal about the use conditions when acquiring the message. At this time, the message control unit 26 acquires the source address of the acquired message, the format of the message, the presence / absence of data attached to the message, the format of the data, the priority of the message, the importance of the message, and the characters included in the message Preferably, the receiving terminal is notified of the column, the message capacity, and the like. The receiving terminal designates at least one of the receiving side condition or the transmitting side condition as a use condition as a response to the inquiry. When selecting based on designation of use conditions by the transmission terminal, the transmission terminal adds the designation of use conditions to the message and transmits it. The message control unit 26 acquires a message including specification of use conditions by the transmission terminal. The message control unit 26 selects a condition specified by the receiving terminal or the transmitting terminal as a use condition.

  Next, the message control unit 26 determines a transmission method of the message to the receiving terminal based on the selected use condition. When the message control unit 26 selects the reception-side condition as the use condition, the message control unit 26 searches the reception-side condition database 23a based on the transmission destination address of the message, and acquires the reception-side condition when the mobile terminal 10a becomes the reception terminal. To do. When there is one reception-side condition, the message control unit 26 compares the determination condition included in the reception-side condition with the message. When the message matches the determination condition, the message control unit 26 determines the transmission method included in the reception-side condition as the transmission method of the message to the mobile terminal 10a.

  When the transmission side condition is selected as the use condition, the message control unit 26 searches the transmission side condition database 23b based on the transmission source address of the message, and acquires the transmission side condition when the MMS terminal 30a becomes the transmission terminal. To do. When there is one transmission side condition, the message control unit 26 compares the determination condition included in the transmission side condition with the message. When the message matches the determination condition, the message control unit 26 determines the transmission method included in the transmission-side condition as the transmission method of the message to the mobile terminal 10a.

  Regardless of whether the reception side condition or the transmission side condition is selected, if the message does not match the determination condition, the message control unit 26 selects a transmission method other than the transmission method specified when the message matches the determination condition. The transmission method to the mobile terminal 10a is determined. That is, the message control unit 26 determines indirect transmission when the designated transmission method is direct transmission, and determines direct transmission when the designated transmission method is indirect transmission.

  For example, when the receiving-side condition or the transmitting-side condition is “directly transmit when the subject or text includes the character string“ emergency ””, the message control unit 26 sets “subject” or “emergency” to “emergency”. If a character string is included and the message meets the determination conditions, direct transmission is determined. On the other hand, the message control unit 26 determines indirect transmission when the subject or text does not include the character string “urgent” and the message does not meet the determination condition.

  In addition, when a plurality of reception-side conditions or a plurality of transmission-side conditions are registered, the message control unit 26 determines a determination condition included in the reception-side condition or transmission-side condition having the highest intra-terminal priority, and a message. Compare. When the message matches a receiving-side condition or a transmitting-side condition determination condition with the highest in-terminal priority, the message control unit 26 sets the transmission method included in the receiving-side condition or transmitting-side condition to the mobile terminal of the message. The transmission method to 10a is determined. If the message does not match the determination condition of the receiving side condition or the transmitting side condition with the highest in-terminal priority, the message control unit 26 determines the receiving condition or the transmitting condition condition with the next highest in-terminal priority and the message. And compare. As described above, the message control unit 26 compares the determination condition included in the reception-side condition or the transmission-side condition with the message in the order of the in-terminal priority order of the reception-side condition or the transmission-side condition. Then, when the message matches the determination condition, the message control unit 26 determines the transmission method included in the reception-side condition or transmission-side condition as the transmission method of the message to the mobile terminal 10a.

  If the message does not match the determination condition of the reception side or transmission condition with the lowest in-terminal priority, the message control unit 26 matches the determination condition of the reception side or transmission condition with the highest in-terminal priority. The transmission method other than the transmission method specified in this case is determined as the transmission method of the message to the mobile terminal 10a. If the message does not match any of the determination conditions, the message control unit 26 determines a predetermined default transmission method or determines a transmission method using a condition that is not selected. Also good.

  When both the reception side condition and the transmission condition are selected as usage conditions, the message control unit 26 first selects the reception side condition, and based on the reception side condition in the same manner as when the transmission side condition is selected. The transmission method on the reception side and the transmission method on the transmission side based on the conditions on the transmission side are determined. When the reception side transmission method and the transmission side transmission method match, the message control unit 26 determines the matching transmission method as the transmission method of the message to the mobile terminal 10a. On the other hand, when the reception side transmission method and the transmission side transmission method are different, the message control unit 26 determines the reception side transmission method and the transmission side transmission method as the transmission method of the message to the mobile terminal 10a. According to this, the message control device 20 satisfies the conditions of both the reception side and the transmission side, even if there is a conflict between the transmission method on the reception side and the transmission method on the transmission side. Transmission can be controlled.

  For example, the message control unit 26 determines indirect transmission when both the reception side transmission method and the transmission side transmission method are indirect transmission, and directly transmits when both the reception side transmission method and the transmission side transmission method are direct transmission. To decide. In addition, when the receiving side transmission method is indirect transmission and the transmitting side transmission method is direct transmission, the message control unit 26 determines indirect transmission and direct transmission, and the receiving side transmission method is direct transmission. When the side transmission method is indirect transmission, direct transmission and indirect transmission are determined.

  Furthermore, it is preferable that the message control unit 26 determines the transmission method of the message to the receiving terminal based on the processing capability of the receiving terminal in addition to the usage conditions. According to this, the message control device 20 can control the transmission of the message to the receiving terminal in consideration of the processing capability of the receiving terminal. In this case, the message control unit 26 first determines a transmission method based on use conditions. Next, the message control unit 26 searches the terminal information database 24 based on the transmission destination address of the message, and acquires the processing capability of the mobile terminal 10a that is the receiving terminal. The message control unit 26 determines whether or not the mobile terminal 10a can process a message transmitted by the transmission method determined based on the use conditions based on the acquired processing capability.

  If the message control unit 26 determines that the message can be processed, the message control unit 26 determines the transmission method determined based on the use condition as the transmission method of the message to the mobile terminal 10a. On the other hand, if the message control unit 26 determines that the message cannot be processed, the transmission method determined based on the use conditions and the transmission method by which the mobile terminal 10a, which is the receiving terminal, can process the message are set as the mobile terminal of the message. The transmission method to 10a is determined. According to this, the message control device 20 is configured so that even if the receiving terminal cannot process the message transmitted by the transmission method determined based on the use conditions, the message can be processed by the receiving terminal without fail. Can be transmitted to the receiving terminal.

  For example, if the receiving terminal can process a message transmitted by either direct transmission or indirect transmission, if the transmission method determined based on the usage conditions is indirect transmission, the message control section 26 sets the usage conditions to indirect transmission. If the transmission method determined based on this is direct transmission, direct transmission is determined. When the message control unit 26 cannot process a message transmitted by direct transmission but can process a message transmitted by indirect transmission, the transmission method determined based on the use conditions is direct transmission. In this case, direct transmission and indirect transmission are determined.

  The definition that the message can be processed can be appropriately set in the message control device 20. For example, when it is determined based on the message format that it is possible to process that all types of processing are possible, that it is possible to process even one type of processing that can be received, and that reception processing can be processed It is possible to define that it is possible to process that all processing is possible, that it is possible to process the entire message, that it is possible to process a part of the message, and that it is possible to process a part of the message. In this way, the definition that processing is possible can be set using the type of processing, the target processing capability, the whole or part of the message, and the like. In the present embodiment, it is possible to process that the entire message can be received and displayed.

  When the determined transmission method is direct transmission, the message control unit 26 inputs the message addressed to the mobile terminal 10a acquired from the MMS relay / server interface 22 to the message server interface 21 and instructs transmission to the mobile terminal 10a. . As a result, the message is transmitted directly to the mobile terminal 10a.

  When the determined transmission method is indirect transmission, the message control unit 26 stores the message addressed to the mobile terminal 10a acquired from the MMS relay / server interface 22 in the message storage unit 27 in association with the address indicating the storage destination. The message storage unit 27 holds a message in association with an address indicating a storage destination. As an address indicating the storage destination, a URL (Uniform Resource Locator) address can be used. Then, the message control unit 26 notifies the mobile terminal 10a of the storage destination and notifies that the message has been stored. Specifically, the message control unit 26 creates a URL notification message that notifies the mobile terminal 10a of the URL address storing the message. The message control unit 26 inputs the created URL notification message to the message server interface 21 and instructs transmission to the mobile terminal 10a. As a result of these processes, the mobile terminal 10a can grasp the storage location and request a message, the stored message is transmitted from the message control device 20, and the message is indirectly transmitted to the mobile terminal 10a.

  When the determined transmission method is direct transmission or indirect transmission, the message control unit 26 performs control so that the entire message is transmitted by both direct transmission and indirect transmission. Alternatively, the message control unit 26 may control to directly transmit a portion that can be processed by the receiving terminal by direct transmission and indirectly transmit the entire message or a portion that cannot be processed by the receiving terminal by direct transmission.

  Further, the message control unit 26 controls the transmission of the message using either the reception side transmission method or the transmission side transmission method, and controls the transmission of the message by the transmission method not used for the transmission based on the transmission result. May be. For example, when one of the reception side transmission method and the transmission side transmission method is direct transmission and the other is indirect transmission, the message control unit 26 first directly transmits the entire message. If there is a part that the receiving terminal could not process by direct transmission, the message control unit 26 controls to transmit the entire message or a part that could not be processed by indirect transmission that was not used for transmission. When the receiving terminal can process the entire message by direct transmission, the message control unit 26 performs control so that indirect transmission not used for transmission is not performed.

  According to these, the receiving terminal can acquire the part that cannot be processed and the whole message by indirect transmission when the part that cannot be processed by direct transmission is included in the message or the whole message cannot be processed by direct transmission. You can get the whole message as Further, in the case of controlling message transmission based on the transmission result, the message control device 20 utilizes the transmission result by the transmission method used for transmission, and does not use only the part that could not be processed for transmission. If the message is transmitted by the method or the entire message can be processed, it can be controlled not to transmit the message by the transmission method not used for transmission, and the transmission method not used for transmission can be used appropriately.

  The message control unit 26 inputs the entire message or a part that can be processed by direct transmission to the message server interface 21 and instructs transmission to the mobile terminal 10a. Further, the message control unit 26 stores the entire message or a portion that cannot be processed by direct transmission in the message storage unit 27 in association with the address indicating the storage destination, and notifies the mobile terminal 10a of the storage destination. At this time, the message control unit 26 acquires the terminal information of the mobile terminal 10a from the terminal information database 24, and determines the part of the message that can be processed by the mobile terminal 10a based on the acquired terminal information. When storing the entire message, the message control unit 26 also stores the portion that can be processed in the message storage unit 27.

  In this way, the message control unit 26 controls message transmission according to the determined message transmission method to the mobile terminal 10a. The message control unit 26 acquires the terminal information of the mobile terminal 10a from the terminal information database 24, converts the message so that the mobile terminal 10a can process based on the acquired terminal information, and then the message server interface 21. Or may be stored in the message storage unit 27. For example, the message control unit 26 converts the format of the message and the format of the data attached to the message into a format that can be processed by the mobile terminal 10a, or the capacity that allows the mobile terminal 10a to receive and display the message. Or convert to

  The indirect transmission control unit 28 controls transmission of messages stored in the message storage unit 27. When receiving a message request from the receiving terminal, the indirect transmission control unit 28 controls to transmit the stored message to the receiving terminal. The indirect transmission control unit 28 acquires a request for a message stored in the message storage unit 27 from the mobile terminal 10a from the message server interface 21. Specifically, the indirect transmission control unit 28 acquires a URL browsing request. The URL browsing request is for requesting a message stored in association with the URL address, and includes a URL address indicating the storage destination of the message. The indirect transmission control unit 28 searches the message storage unit 27 based on the URL address included in the URL browsing request, and acquires a message addressed to the mobile terminal 10a. Then, the indirect transmission control unit 28 inputs the acquired message addressed to the mobile terminal 10a to the message server interface 21 and instructs transmission to the mobile terminal 10a. Further, the indirect transmission control unit 28 notifies the message control unit 26 that the message has been transmitted to the mobile terminal 10a.

  Note that the URL browsing request may include a notification from the mobile terminal 10a to the message control device 20 regarding a portion that the mobile terminal 10a can process by direct transmission. In this case, the indirect transmission control unit 28 inputs only the unprocessable part to the message server interface 21 except for the part that can be processed from the message stored in the message storage unit 27, and transmits the message to the mobile terminal 10a. Instruct. Further, the indirect transmission control unit 28 stores in the message storage unit 27 where the notified processable part is.

  In the case of direct transmission, the message control unit 26 acquires a message delivery notification from the message server interface 21. In the case of indirect transmission, the message control unit 26 receives notification from the indirect transmission control unit 28 that the message has been transmitted to the mobile terminal 10a. Thus, when the message control device 20 receives a message delivery notification or transmits a message stored in the message storage unit 27 to the mobile terminal 10a, the message control unit 26 sends a delivery confirmation notification to the MMS terminal 30a. create. When both direct transmission and indirect transmission are performed, the message control unit 26 may create both a delivery confirmation notification when performing direct transmission and a delivery confirmation notification when performing indirect transmission. Only one of them may be created. The message control unit 26 inputs the created delivery confirmation notification to the MMS relay / server interface 22 and instructs transmission to the MMS terminal 30a.

  When a message is transmitted from the mobile terminal 10a to the MMS terminal 30a, the same processing as described above is performed except that the processing direction is changed from the mobile terminal 10a to the MMS terminal 30a.
